use-note

Musical note spelling metadata primitives for RustUse.

Experimental

use-note is experimental while use-music remains below version 0.3.0.

Example

use use_note::{Accidental, NoteLetter, NoteName, Octave};

let note = NoteName::new("C#4")?;
let octave = Octave::new(4)?;

assert_eq!(note.as_str(), "C#4");
assert_eq!(note.letter(), NoteLetter::C);
assert_eq!(note.accidental(), Accidental::Sharp);
assert_eq!(note.octave(), Some(octave));
# Ok::<(), use_note::NoteError>(())

Scope

• Note letters, accidentals, octave values, note names, note spellings, and scientific pitch notation.
• Lightweight parsing for common spellings such as C, C#, Db, F##, Gbb, A4, and C#4.

Relationship to use-acoustics

use-note models symbolic note spellings only. Physical frequency and sound calculations belong in use-acoustics and wave behavior belongs in use-wave.

Non-goals

• Calculating frequency, wavelength, pitch detection, audio playback, MIDI I/O, or synthesis.
